My head is going to explode, can someone help before it is too late?
Te problem:
According to the government, 23% of all American adults have more than one job. A random survey of 68 adults finds that 21 of them hold more than one job. At the 5% level of significance, can we accept the government's claim?
Let me see, I have the (sorry don't know how to write formula on here)
H0: mu = .23 which is the stated average by the government.
H1: mu not = .23
alpha = 0.05
n= 68
x bar= .309 (percentage of sample 21/68 = .309)
I am at a loss here. Maybe I am stupid, but I don't see enough info to get a standard deviation and complete the problem. Am I missing something? Someobody help me please.
By the way... there are a few more problems I will post seperately because I am dying here.
